Attempting to shut the system down (e.g. 'poweroff') does everything,
including turning the light on the front system off, but never quite
fully powers the machine off. I have to hold the power button down for
about 5 seconds to actually properly turn it off.
This behavior has been observed by myself and others with an Intel Mac Mini.
I was originally seeing this issue with a Cinergy T2 device but have
now also witnessed it with an MSI Mega Sky 580 and a Pinnacle PCTV
Diversity (note, all of these are USB devices).
The source if the problem was only revealed by the PCTV Diversity
driver, on failed shutdowns following the usual:
Sending all processes the TERM signal
Sending all processes the KILL signal
I receive a stream of the following message:
stk7700d:RC Query Failed
Commenting the remote control handling out of the PCTV Diversity
driver has 'solved' the shutdown problems, shutdown is now 100%
reliable.
Any suggestions as to the root cause of this issue or a 'solution'
other than manually removing RC handling from the drivers would be
greatly appreciated.
